Quick efficient sludge dewatering device

Abstract

The invention discloses a fast and high-efficiency sludge dewatering device, which comprises a shell, the bottom of the shell is symmetrically arranged with supporting feet, and a screen is arranged inside the shell, and the screen is in the shape of an arc groove. A turntable is set at the center of the arc, and the turntable is set on a rotating shaft in the casing. A rotating rod is arranged symmetrically on the center of the turntable, and a scraper is arranged at the end of the rotating rod. The top end of the right side of the screen is fixed on the casing. On the right side wall of the body, the left end of the screen is fixed to the inner bottom of the housing through a vertical rod; the top of the right side of the housing is provided with a feed port, and the housing on the left side of the screen is provided with an upper extrusion roller and a lower extrusion roller; The lower squeeze roller includes an outer drum, and the outer drum is a filter mesh drum; the invention skillfully arranges the screen structure and the scraping mechanism on the screen, which greatly improves the sludge dewatering efficiency, and at the same time, an upper squeeze roller is arranged corresponding to the bottom of the screen. The pressure roller and the lower squeeze roller, and clever use of the material hanging mechanism to scrape in the preliminary dewatered sludge to achieve further dehydration.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a fast and efficient sludge dewatering device. Background technique [0002] With the continuous improvement of my country's urbanization level, the construction of sewage treatment facilities has developed rapidly. According to the "2013-2017 China Sludge Treatment and Disposal In-depth Research and Investment Strategic Planning Analysis Report" statistics, in 2010 my country's urban sewage treatment plants have built 2500 The urban sewage treatment capacity has reached 122 million tons per day, which has made great contributions to the realization of the country's emission reduction goals and improvement of the water environment. However, the construction and operation of the sewage plant will produce a large amount of excess sludge. Based on the water content of 80%, the total annual sludge water production in the country will soon exceed 30 million t...
